Hydrangea HIHAI Compact Sturdy Growth Habit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Hydrangea macrophylla cultivars lack sturdy and compact plants with durable inflorescences and optimal post-production longevity, which are essential for attractive and long-lasting floral displays.
Innovation Solution
A new cultivar, 'HIHAI', resulting from a cross-pollination between proprietary selections of Hydrangea macrophylla, exhibits a compact, upright growth habit, strong stems, and dense, white-colored sterile flowers with improved durability and longevity, achieved through asexual reproduction by terminal vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional Hydrangea macrophylla cultivars are used, then they can be grown under standard conditions, but they lack sturdy stems and compact growth habit
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific morphological parameters - compact growth habit, upright posture, and sturdy stem structure. The cultivar 'HIHAI' exhibits these modified parameters compared to conventional cultivars, achieving the desired strength and compactness through controlled breeding that alters plant architecture parameters.
2Duration of action of stationary object
If conventional Hydrangea macrophylla cultivars are used, then they can produce flowers, but the inflorescences lack durability and post-production longevity
Solution Approach 1:
The patent improves inflorescence durability and longevity by changing the physiological and structural parameters of the inflorescences. The cultivar 'HIHAI' produces inflorescences with enhanced structural integrity and extended vase life, achieving both reliability and extended duration through selective breeding that modifies flower persistence parameters.
